How would I write the line of equation for (0.5,4.5) and (8,0.5)

Mathematics
1 answer:
Pepsi [2]3 years ago
8 0

Answer:

Step-by-step explanation:y – y1 = m(x – x1)     * substitute (-0.5, 4.1) for x1 and y1

y - (4.1) = (0.8)(x - (-0.5))    

y - 4.1 = 0.8(x + 0.5)     * distribute the 0.8

y - 4.1 = 0.8x + 0.4     * add 4.1 to both sides

y = 0.8x + 4.5

this is the example hope this helped!

The sum of the angle measures of a quadrilateral is 360°. Write and solve an equation to find the value of X.​
uranmaximum [27]

Answer:

1). x° + 100° + 120° + 100° = 360°

2). x = 40

Step-by-step explanation:

Formula for the sum of the interior angles of a polygon = (n-2)\times 180

Where n = number of sides of the polygon

From the picture attached,

For n = 4,

Sum of the interior angles of the given polygon = (4 - 2) × 180°

                                                                                = 360°

Therefore, equation for the sum of interior angles will be,

x° + 100° + 120° + 100° = 360°

x° + 320° = 360°

x° = 360° - 320°

x° = 40°

Write the equation of the line perpendicular to 4x – 5y = -10 through the point (2, 3). explain please
Snezhnost [94]

Answer:

y =-5/4x +11/2

Step-by-step explanation:

First we need to find the slope of the line

4x-5y = 10

Solve for y

Subtract 4x from each side

4x-4x-5y =-4x-10

-5y = -4x-10

Divide by -5

-5y/-5 = -4x/-5 -10/-5

y = 4/5x +2

The slope is 4/5

The slope of a line that is perpendicular is the negative reciprocal

m perpendicular = - (5/4)

We know have a slope = -5/4 and a point (2,3)

We can use the point slope form of a line

y-y1 = m(x-x1)

y-3 = -5/4 (x-2)

Distribute

y-3 =-5/4x +10/4

Add 3 to each side

y-3+3 = -5/4 x +5/2 +3

Get a common denominator

y = -5/4x +5/2 +6/2

y =-5/4x +11/2

Adam bought a fish aquarium worth $2,000 in the first week of the year. Its value depreciates by 3% per
scoray [572]

Answer:

The answer is 1825.35

Step-by-step explanation:

Since the first week isn’t included, we only count 4 weeks.

So first, 2000 x 0.03 = 60

(By the way 0.03 is 3%)

2000 - 60 = 1940

Subtracting 2000 by 60 represents the amount of money the aquarium went down in that week.

Then, week 3:

1940 x 0.03 = 58.2

1940 - 58.2 = 1881.8

Now, the last week, week four:

1881.8 x 0.03 = 56.45

1881.8 - 56.45 = 1825.35.

Therefore, 1825.35 after 5 weeks.
